Kicker 46CXA4001 CXA4001-400-Watt Mono Class D Subwoofer Amp

Great amp. Small size makes for an easy install.

After several amps failed and overheated within 45 min this one goes for hours. No thermal shutdown, bass is crisp and clear, just impressive all the way and for this price is crazy.

Very powerful amplifier for the money, and a solid brand to purchase. This amp is mono so it combines left and right signals passed into it; the subwoofer low-pass filter that's built-in works well; the bass boost control is a nice feature; and there's plenty of gain to match your installation requirements. The amplifier effortlessly pushes a 2-ohm load to its 400W RMS rating and a bit more while getting only slightly warm to the touch.

Using to power one ten inch sub, doesnt even get warm but I dont listen to bass intensive music. Biggest selling point for me was the voltage for high level inputs. My inputs are from an Amp/Dsp and I dont even have to turn the input gain down in DSP. Strong signal made a clean input and the amp take it well.

Overall a good amp. Kicker quality I’ve known and loved over the years. Solid amp for those are just want to power a subwoofer and don’t care to let everyone on the block know. 2 personal gripes I have with this amp that lead me to knock off a star. 1. 1/8 aux cable style remote knob. They are known to pull out if pulled. Also keep in mind that the knob is not included. 2. Power and ground use fork terminals. This is more preference. While fine on smaller wire, im just not a fan for the 8awg power and ground terminals. That’s just me though.

Installed this in my 2016 Ram 2500 Laramie Power Wagon using the Rockford Fosgate RFI2SW high level RCA input adapter. These amps use Kickers FIT+ (2019 and up) technology so it can accept up to 40VDC high input signal and does not require a LOC and uses DC offset for remote turn on. This little amp is rated @ 525 Watts RMS so is perfectly matched for the sub I used. Kicker never disappoints! Extremely easy to install and works very well in this setup. Use full spec 8AWG wire for install to avoid overheating and blown fuses! Highly recommended!

Bought after I was gifted a kicker 10" comp sub and it works great, even with it mounted in the rear of my trunk with no ventilation and plenty of dust

Picked up this amp to run with the skar 10" sub made for the Tacoma. Perfect combo! 400 watts RMS at 1ohm paired with the 1ohm 10" gives excellent bass and perfect fit! Amp fits nicely under the back passenger seat storage, I just moved the jack that was there to the other side, ran the amp power under the passenger side door plates, under the carpet into the storage area. Ran the RCA under the driver side. Great little amp for the price!
